SOLID HEAT CARRIER CATALYST FOR THERMAL DESORPTION OF ORGANIC MATTER-CONTAMINATED SOIL AND METHOD FOR PREPARING SAME - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240050928 titled 'SOLID HEAT CARRIER CATALYST FOR THERMAL DESORPTION OF ORGANIC MATTER-CONTAMINATED SOIL AND METHOD FOR PREPARING SAME

Simplified Explanation

The abstract describes a patent application for a solid heat carrier catalyst used for thermal desorption of organic matter-contaminated soil. The catalyst is prepared by using a hollow alumina ball made through 3D printing as the solid heat carrier, a copper-nickel-vanadium composite oxide as the catalytic active component, and vinyltriethoxysilane as a masking agent. The ball is masked on its outer surface with vinyltriethoxysilane and then pierced to create channels connecting the inner surface with the outside. The ball is then immersed in a precursor solution of the catalytic active component and subjected to drying and calcination to obtain the solid heat carrier catalyst.

• The patent application describes a method for preparing a solid heat carrier catalyst for thermal desorption of organic matter-contaminated soil.
